Spherical mirror is categorised into two forms, namely: Concave and Convex. Copyright Notice © 2020 Greycells18 Media Limited and its licensors. An object placed in front of a mirror generates an image. or f = -30/4 = -7.5 cm By mirror formula,   If light rays from the object fall on the mirror and are then reflected and converge to form an image, the image thus formed is a real image. From the image position formula, we find: f = o*I/(o+I) = 25 cm * 100 cm2 /(125 cm), then the curvature radius is r ≈ 2 * f = 40 cm. Define New Cartesian Sign convention, object/image distance, mirror formula... Queries asked on Sunday & after 7pm from Monday to Saturday will be answered after 12pm the next working day.   As such, using ray diagrams, it is possible to determine the type of image formed, while using concave and convex mirrors, based on the distance of the object from the mirror. (1) . findthe size nature and position of image formed when an object of size 1 cm is placed at a distance of 15from a fro from a concave mirror of focal length 10cm cm from a concave mirror of focal length in centimetre from a concave mirror of, why can't we write mirror formula as f = v + u, In which part of mirror we will take positive and negative sign?In or f = -30/4 = -7.5 cm m = -3, u = -10 cm the image distance is equal to the object distance and the image is on the back side of the plane mirror. Don’t worry, let us know and we will help you master it.

Mirror formula is an equation which shows relationship between focal length (f), object distance(u) and image distance(v) in case of spherical mirror.   Expert Answer: By mirror formula, we have v = - u, i.e. Image distance is the distance of the image from the pole of the mirror and it is denoted by the letter v. And focal length is the distance of the principal focus from the pole of the mirror. 1/f = 1/v + 1/u = 1/-30 + 1/-10 = -4/30   Distances measured along the direction of the incident ray are positive. Object distance is the distance of the object from the pole of the mirror; denoted by the letter u. To obtain exact information about the size and magnification of the image, and the distance of the image from the spherical mirror, we can use the mirror formula. The mirror formula for a concave mirror is given below. Distances are to be measured from the pole (vertex) of the mirror marked by point V in the figure. If light rays from the object fall on the mirror and are then reflected and converge to form an image, the image thus formed is a real image.
